Farmacodinâmicas
Farmacodinâmicas refers to the study of the biochemical and physiological effects of drugs on the body. It investigates how drugs interact with their targets at a molecular level, such as receptors, enzymes, or ion channels, and the subsequent cascade of events that lead to a therapeutic or toxicological outcome. This field aims to understand the mechanism of action of a drug, its potency, efficacy, and the relationship between drug concentration and its effect. Pharmacodynamics also encompasses the study of drug tolerance, resistance, and interactions with other substances. Understanding these principles is crucial for optimizing drug therapy, predicting patient responses, and developing new medications. It helps determine the appropriate dosage, frequency, and route of administration to achieve the desired effect while minimizing adverse reactions. The study of pharmacodynamics is a cornerstone of pharmacology and rational drug design.
